DOA -- Two Versions -- At Work Here
DOA was made twice...once with Edmond O'Brien way back in 1949..and a remake in 1988 with Dennis Quaid. Both films played out their grim premise -- the hero has been poisoned and has hours to find out who dunnit and get revenge -- by letting the hero die.
So evidently DOA was "injected" into this Tough Chick Action Movie.
Makes it different.
